I'd like to make an input for my blaupunkt deck. I found these connectors but am not really clear on how to solder them. From this pick, it looks like the cup side is already filled with solder or is super shallow. Anyone have experience with these?

To make matters worse. The plugs that I have (purchased from vetco, same as this pic) actually don't appear to have the shallow cups. In the store (without my glasses) it looked like they were just pins with no accommodation for soldering. Are they likely just filled to the brim w/ solder?

YouTube is usually the DIY best friend, but surprisingly it doesn't seem to have anything about soldering these up. Anyone here more experienced with these?

thanks

I design and build custom audio equipment for recording studios and audio engineers, so a large portion of my time is spent soldering circuit boards and audio connectors. I have never seen a connector that comes pre-filled with solder. I'm pretty sure such a thing doesn't exist. As a tech I could tell you that something like that would irritate me if it did. Who knows the quality or composition of the solder that's in it. I only use SN62, and i dont want some 60/40 in anything i build. What if your product had to meet ROHS standards, and the solder in there was lead bearing? I'd never buy a product like that if it did exist , but I really don't think it does.

Easiest way to solder this is to use a table clamp to firmly hold the connector in place. Fill the cups with solder. Strip and tin the wires to be soldered. Then heat the cups until the solder melts and insert the tinned wire. EZ-PZ.

For the ones that don't have cups, tin the wire and hold the wire against the pin with your soldering iron. The solder from the tinned wire will hold it to the pin. A table clamp is mandatory for this.
Also using a pencil iron (min 30 watts, preferably 40 watts) and thin solder not thicker then 0.7mm makes the job easier.

And don't forget to put the rubber boot on the wire before you solder it to the connector!!!
